I installed it on a 32" TCL Roku TV and Roku branded soundbar. Align them with the screw holes on the soundbar when using all four screw holes on the TV. I didn't want to just attach the bracket to the TV's two screw holes so that it would reach the soundbar's screw holes. I took one of the carriage bolts that connect the long and short pieces together on either side to allow the short pieces to rotate further than the second bolt will allow. The kit only came with two M4 bolts and I needed four Holes and grooves in the long mounting brackets are wide enough to allow the M4 washers included in the kit to fall through. All of the included screws are metric and my soundbar is 1/4"x20. I had to buy more M4 screws, M4 washers and 1/4"-20x0.5" screws to attach the TV and To fit soundbar mounting brackets The instructions were very good confusing it was much easier if I ignored them.
